What value is stored in an initialized but empty integer array in Java

Issue

I made the following array:

int[] array = new int[9];

This array is initialized, but empty.

In that case, what is the value of any index of this array?

When I print it out, it gives me 0.
Does that mean there is a zero stored in here (like if you had called int x = 0)?
Or is it null?

Also, is this the same for any Object array?
Is it an empty instance of this object, or is it null?

Solution

If it is an Array of objects it will be initialized with null, if it's an array of primitive values (like int) it will be initialized with 0. For the non-number primitive boolean it is false and for 'char' it is '\u0000'. For more information, check the table Default Values on the following page:
